Konstantin Shaposhnikov created SPARK-8122:
----------------------------------------------
Summary: A few problems in ParquetRelation.enableLogForwarding()
Key: SPARK-8122
URL: https://issues.apache.org/jira/browse/SPARK-8122
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 1.5.0
Reporter: Konstantin Shaposhnikov
_enableLogForwarding()_ should be updated after parquet 1.7.0 update , because
name of the logger has been changed to `org.apache.parquet`. From parquet-mr
Log:
{code}
// add a default handler in case there is none
Logger logger = Logger.getLogger(Log.class.getPackage().getName());
{code}
Another problem with _enableLogForwarding()_ is that it doesn't hold to the
created loggers that can be garbage collected and all configuration changes
will be gone. From
https://docs.oracle.com/javase/6/docs/api/java/util/logging/Logger.html
javadocs: _It is important to note that the Logger returned by one of the
getLogger factory methods may be garbage collected at any time if a strong
reference to the Logger is not kept._
